Snowflake is a cloud-based elastic data warehouse or Relational Database Management System (RDBMS). Snowflake enables data storage, processing, and analytic solutions that are faster, easier to use, and far more flexible than traditional offerings. Snowflake supports both transformation during (ETL) or after loading (ELT). Snowflake works with a wide range of data integration tools, including Informatica, Talend, Tableau, Matillion and others.
